Fig. 2From: FDM simulation of earthquakes off western Kyushu, Japan, using a land–ocean unified 3D structure modelDetails of seismicity in the rectangular area shown in Fig. 1 with orange dotted lines based on the unified focal parameters determined by JMA: a distribution of the earthquakes (M JMA ≥2 and depths ≤30 km) from 11/14/2005 to 11/13/2015 (JST), i.e., 10 years prior to the 11/14/2015 M7.1 event. b Twenty-four-hour aftershocks of the M7.1 event (EV1). c One-week aftershocks of EV1 from 11/14/2015 to 11/20/2015 (JST). d One-month aftershocks of EV1 from 11/14/2015 to 12/13/2015 (JST). e Activity from 11/14/2015 to 04/13/2016 (JST), i.e., just before the onset of the Kumamoto earthquake sequence. f Activity from 04/14/2016 to 06/30/2016 (JST), i.e., after the onset of the Kumamoto seismic activity. The events beginning with a M5.0 event on 05/06/2016 (Fig. 3a) are drawn with orange circles Back to article page
